Abstract
An easily assembled, aesthetically pleasing ceiling fan has a main support shaft which supports an outer decorative column and canopies as well as a drive motor having a rotor mounting a blade support housing and carrying easily attachable fan blades. A bottom cover is also supported from the shaft for ease of assembly and providing a surface configuration coordinating with the canopies and blade support housing.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1. A ceiling fan assembly comprising: (a) a ceiling fixture attachable to a ceiling structure; (b) a shaft having one end shaped to hang vertically from the ceiling fixture; (c) a support hub attached to the other end of .[.the hollow.]. .Iadd.said .Iaddend.shaft; (d) a column assembly supported from the hub and including an elongated vertical hollow column surrounding and spaced from the shaft, and further including a partly spherically shaped canopy at a lower end thereof; (e) an electric fan drive motor carried by the lower end of the shaft, the motor having a drive rotor; (f) a fan blade support structure positioned below said canopy, the fan blade support structure including a partly spherical blade support housing having spaced fan blade mounting slot therein, the support structure including means for attaching the support structure to the motor rotor and means for attaching fan blades to said support structure; (g) a plurality of fan blades having attachment means on the inner end of each blade for attachment to blade support structure; (h) a partly spherical bottom cover assembly positioned below the fan blade support structure for at .[.lease.]. .Iadd.least .Iaddend.partially covering the bottom of the motor while being spaced therefrom, the bottom cover supported from the bottom of the shaft.Iadd., .Iaddend.the combination of said canopy, said fan blade support housing and said bottom cover assembly surrounding said drive motor and providing the appearance of a ball.
2. A ceiling fan as in claim 1 wherein the column assembly further includes an upper canopy spaced from and at least partially enclosing the ceiling fixture.
3. A ceiling fan as in claim 1 wherein the support hub is a flanged hub, the flange of which mounts the column assembly.
4. A ceiling fan as in claim 3 further including means for detachably attaching the support hub to the shaft for ease in assembly.
5. A ceiling fan as in claim 2 wherein the upper canopy is partly spherically shaped.
6. A ceiling fan as in claim 1 wherein the upper end of the vertically hanging shaft is part spherically shaped.
7. A ceiling fan as in claim 1 wherein the bottom cover assembly includes a pan attached to the lower end of the shaft and wherein the bottom cover is removably attached to the pan.
8. .Iadd.A ceiling fan assembly comprising: a ceiling fixture attachable to a ceiling structure; a shaft having one end shaped to hang vertically from the ceiling fixture; a support hub attached to the other end of said shaft; a partly spherically shaped canopy supported by said support hub; an electric fan drive motor carried by the lower end of the shaft, the motor having a drive rotor; a partly spherical fan blade support structure having spaced fan blade mounting slots therein the securely retaining fan blades, and means for attaching said support structure to said drive rotor; a plurality of fan blades each having attachment means on an inner end thereof for attachment to said blade support structure; and a partly spherical bottom cover assembly positioned below said fan blade support structure for at least partially covering the bottom of the motor while being spaced therefrom, the bottom cover supported from the bottom of the shaft; the combination of said canopy, said fan blade support structure and said bottom cover assembly surrounding said drive motor and providing the appearance of a ball. .Iaddend.
9. .Iadd.A ceiling fan assembly comprising: a ceiling fixture attachable to a ceiling structure; a shaft having one end shaped to hang vertically from the ceiling fixture; a support hub attached to the other end of said shaft; a canopy supported by said support hub, the canopy having its outside surface shaped in the form of a first portion of a unitary geometrical shape; an electric fan drive motor carried by the lower end of the shaft and positioned within said canopy, the motor having a drive rotor; a fan blade support structure having its outside surface shaped in the form of a second portion of said unitary geometrical shape, including spaced fan blade mounting slots therein, and means for attaching said support structure to said drive rotor; a plurality of fan blades each having attachment means on an inner end thereof for attachment to said blade support structure; and a bottom cover assembly having its outside surface shaped in the form of a third portion of said unitary geometrical shape, positioned below said fan blade support structure and at least partially covering the bottom of the motor while being spaced therefrom, the bottom cover supported from the bottom of the shaft; the combination of the outside surfaces of said canopy, said fan blade support structure and said bottom cover assembly combining to produce a smooth unitary uninterrupted surface so that fan blade support structure appears on the surface as a continuum of the adjacent surfaces of the canopy and bottom cover assembly. .Iaddend.Join the waitlist — get patent alerts
